The effects of coherent radiation on a general molecular system are studied by evaluating the influence functional of the field. It is shown that the quantized radiation field is equivalent to a classical driving term plus a dissipative term equivalent to that of the vacuum state. It is thus concluded that the dissipative character of quantized radiation cannot be controlled by adjusting the intensity of the beam.
